THE CAT ATE THE RAT
THE ACA TAT ETH ERA T == ADDING “A”
THC ATA TET HER AT = REMOVAL OF “E”
THC EAT ATE THE RAT = SWITCHING E WITH C
Q1. What is the function of replication?
The process where DNA is copied during the cell division is
called “Replication”.
Note. This will only take place during the cell division during the
S phase (Mitosis)
Function: it assures that 46 chromosomes are properly copied
and when it divides it into 2 cells, both cells gets the exact copy
of the parent DNA. There should be no change.
Q2. Explain how DNA serves as its own template during
replication.
Answer: When the replication process starts, the enzymes
begin to unzip the double helix at origins of replication.
Hydrogen bonds are broken between nucleotides and the two
strands are separated.
DNA polymerase enzyme starts bonding new nucleotides with
the old strand nucleotide and develop new complementary
strands to each template.
Q3: How many types of nucleotides are in DNA, and how do
they differ?
Answer: 4 – Adenine, Guanine, Thymine and Cytosine. C and T
has same single ring structure. A and G have a larger double
ring structure.
